AI Technical Summary

Benefits of technology

The present disclosure provides a release mechanism for a door lock system that allows the locking member to move between a secured position and an unsecured position. The mechanism includes a follower assembly with a first locking element and a second locking element, and a support assembly that can move between a proximal position and a distal position. The follower assembly is attached to the locking member and can move it between the secured and unsecured positions. The release mechanism also includes a second actuator assembly that can move the support assembly between the distal position and the locked position. The method of managing access through a door involves activating the actuator of the first actuator assembly to move the locking member to the secured position and activating the actuator of the second actuator assembly to unlock the follower assembly. The follower assembly can then be moved from the engaged position to the release position to allow the locking member to be in the unsecured position. The technical effect of this invention is to provide a more convenient and efficient way to manage access through a door lock system.

Problems solved by technology

However, the redundant actuator and / or port must rely on the integrity of the other components of the locking mechanism to open the door.

example 1

[0023]This example describes a lock release system, see FIG. 1.

[0024]FIG. 1 is a block diagram of an illustrative system, generally indicated at 10, including an illustrative component 12, and an illustrative locking member 14. Component 12 may be able to move between a first position 16, indicated by a solid line in FIG. 1, and a second position 18, indicated by a dashed line in FIG. 1. The first and second positions may be different. Locking member 14 may be able to move, in this case from a secured position 20, indicated by a solid line in FIG. 1, to an unsecured position 22, indicated by a dashed line in FIG. 1.

[0025]When locking member 14 is in the unsecured position, component 12 may move freely between the first and second positions 16 and 18 as indicated by arrow 24. When system 10 is in a configuration where component 12 is in first position 16 and locking member 14 is in secured position 20, component 12 may be prevented from moving by locking member 14.

[0026]System 10 may...

example 2

[0035]This example describes a lock release mechanism and methods of operation of the lock release mechanism, see FIGS. 2-9.

[0036]FIG. 2 is a side view of an illustrative apparatus, generally indicated at 100, attached to an illustrative locking mechanism, generally indicated at 102, showing a follower assembly 104 of the illustrative apparatus in an engaged position.

[0037]Apparatus 100 may be a release mechanism that allows a locking member 106 to alternately, and repeatably, release and capture a component, such as a door. Locking mechanism 102 may allow the locking member 106 to alternately and repeatably release and capture the component. Release mechanism 100 and locking mechanism 102 may be configured to operate independently from one another, having separate activation mechanisms and / or power sources. Either of release mechanism 100 or locking mechanism 102 may be configured to release the locking member while the other is maintained in a locked position. That is, release mec...

example 3

[0067]This example describes a method of managing access through a door, which may be used in conjunction with any of the systems, methods, or apparatuses described herein, see FIG. 13.

[0068]FIG. 13 depicts multiple steps of a method, generally indicated at 200, of managing access through a door. Although various steps of method 200 are described below and depicted in FIG. 13, the steps need not necessarily all be performed, some steps may be repeated, and in some cases may be performed in a different order than the order shown.

[0069]Method 200 may include a step 202 of activating an actuator of a first actuator assembly. The first actuator assembly may be activated to move a piston from a second position in which a locking member is in an unsecured position that allows the door to be moved between closed and open positions, to a first position in which the locking member is in a secured position that secures the door in the closed position. For example, the first actuator assembly ...

Abstract

Systems, apparatuses, and methods of releasing doors that are locked in a closed position. The apparatus may include a follower assembly movably attached to a locking member that moves between a secured position and an unsecured position. The follower assembly may include a first locking element. The apparatus may additionally include a second locking element configured to move between a locking position in which the second locking element engages the first locking element, and an unlocking position in which the second locking element is spaced from the first locking element. The apparatus may further include a support assembly configured to move between a proximal position in which the support assembly supports the second locking element in the locking position, and a distal position in which the support assembly allows the second locking element to move from the locking position to the unlocking position.

Description

FIELD[0001]This disclosure relates to release systems, methods, and apparatuses. More specifically, disclosed embodiments relate to release systems, apparatuses, and methods for opening doors that are locked in a closed position.INTRODUCTION[0002]A locking mechanism may be used to secure a movable component in a particular position, such as a door in a closed position. For example, a locking mechanism may be used on an aircraft to secure doors (e.g., landing gear doors, ordinance compartment doors, etc.) in a closed position. Those locking mechanisms may sometimes be referred to as “door capture lock mechanisms.”[0003]Situations may occur in which the door must be moved to an open position while the locking mechanism still has the door secured in the closed position. Thus, a locking mechanism may include a redundant actuator and / or redundant port to allow the door to be moved to an open position in those situations. However, the redundant actuator and / or port must rely on the integr...
